Vocal Arrangements

Since 2007, I’ve been creating multi-voice arrangements for the a cappella groups that I’ve been involved in. All of these arrangements were created by me (sometimes with the help of friends) for non-commercial purposes. These songs have been sung by Take it SLO in San Luis Obispo, California and Seatown Sound in Seattle, Washington. Please feel free to download, alter, and reproduce my works. If you would be so kind as to credit the original artist and myself that would be just peachy.

Analyzing the relationship between retail pot sales and call-center data

For years, the criminalization of Marijuana sale and usage has made data collection and research on the topic difficult to perform.
